Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main flavour and body of the sauce as they release gelatine and savour during simmering.
- Stock
- Forms the liquid base that carries the flavours and dissolves the richness of the eels.
- Ham
- Adds savoury, salty depth to the stock.
The step that matters
Simmer gently. A gentle simmer extracts flavour and gelatine slowly while keeping the liquid clear. A hard boil makes the sauce cloudy and can break down the eel too quickly, giving a harsher, greasier result.
Swap the onion
How well each one fits the dish's main ingredients (ham, carrot, pepper):
- Capsicumfits better
- Parsnipfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against ham, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes.
